Ireland winger James McClean has labelled Liverpool boss Jurgen Klopp "a bit idiotic" after the German refued to shake West Brom manager Tony Pulis's hand last Sunday.
The Merseysiders played out a 2-2 draw with the Baggies, only snatching a point thanks to Divock Origi's deflected 96th minute strike in a tempestuous Premier League encounter.
McClean condemned the German's behaviour, and said he should have been more respectful
"I've got a lot of respect for the man because he done a great job at Dortmund," McClean said.
"But I think he is a bit of an idiot to be honest after the game on Sunday. Win, lose or draw you have got to be respectful."
Klopp was extremely animated on the touchline throughout the clash, gathering his players at the final whistle to salute the Kop.
Afterwards he defended his decision not to shake Pulis's hand, saying: "I didn't see him after the game. I can say nothing. We had some words in the game; sometimes it takes more than a few seconds to cool down. Usually I shake hands, I did not today because it was not a friendly game."
McClean's rich vein of form of late has drawn praise from Pulis.
"James has become a favourite here at the Hawthorns through his challenges and the way he picks up the ball," the ex-Stoke City boss said.
"I have been delighted with him and he has been fantastic for us."
